This would end up as hideous misfeature as you can't guarantee the
device to show up *at* *all*.
The reason udev is there is that we can dynamically respond to created
device nodes and devices that show up. They might have changed since
the last boot. Maybe they don't show up at all.
Thus you should trigger your actions from /etc/dev.d.
